What would cause my 2001 Chrysler town and country's heat-ac blower control to only work on high speed For both the front and rear controls. Could be as simple as a fuse or is it the control panel?

behind the glovebox is a resister that has malfunctioned. just happened to mine and i explained the problem to oriellys auto parts guy and he told me exactly what it was. i think it is a heater blower resister or something similar. takes 1 minute to replace. really really easy.
I don't know how the Chrysler is wired, but I just fixed a problem like this today on my 1991 Subaru Loyale. The solution may be similar for your Chrysler if you have a four-position switch instead of the expensive electronic controls. I found your question while I was Googling for more information.
In the Subaru, the four position blower switch on the dash selects between taps on a set of three resistors in series, which in this case are open wire coils that sit in the air duct from the fan under the glove compartment. These coils get hot, and get corroded and fragile with age. In my case, the two resistors that connect between switch position 1 and switch position 2 and switch position 3 were both broken and open circuit, meaning that in positions 1 and 2 there was no power to the blower motor. The resistor coil between switch position 3 and 4 was corroded but intact, meaning that switch position 3 and switch position 4 (which bypasses all the resistors) worked properly. There appeared to be some old leaf debris around the coils; I suspect the tannic acid from the leaves contributed to the corrosion and failure.
My local Subaru dealer had a replacement resistor set with a short wiring harness for $44. I removed three screws and unplugged a 4 wire plug, put in the new part, and I was good to go. All 4 positions work now.
Perhaps I could have got some Nichrome wire and made my own resistors and saved some money. I was tempted to build my own electronic control (I am an electronics engineer and could design a high efficiency "switcher" circuit that would save power) but that would be time consuming, and life is short...
While researching my own fix, I found pictures on the web of similar setups for American cars, so this is apparently pretty common. If you look for the part online, look for a "blower resistor" among the heat-ac parts.
If you are agile enough to work upside down under your dashboard (or wherever they put the resistor on your air ducts) this is not a difficult repair. Good Luck!

Why would the recirculation blower come on when you turn the climate controls power off in your 2003 Chrysler Town and Country Lxi with automatic temperature control?
The blower resistor has failed. The resistor is located behind the glove box.
Why does fan blower stay oh high on 2003 Chrysler town and country?
The blower control module has gone bad. Carquest has a new one for $20-$25 dollars.
What is and where is the blower fan control module?
I have an 89 Delta 88 and if you have Electronic Climate Control there is a control module located just right(passenger side) of center at the firewall. It is in the same location as the blower fan resister assembly on a car with standard a/c controls.
What makes the blower motor keep running even with the control switched to the off position?
When that happens on a Chrysler Town and Country with auto temperature, the blower motor power module has failed. It is also called a blower motor resistor.
Is a heater module and a blower resistor the same?
No. An AC/heater control module is a computer that controls and automates the operation of the heating, ventilation, and air conditioning systems (HVAC).The blower resistor enables the blower motor to change the speed of the fan.
Why does the 2003 Chrysler Pacifica blower motor making a growling noise?
No such thing as a 2003 Chrysler Pacifica. Your 2004 Chrysler Pacifica that was built in 2003 probably has a bad bearing in the blower motor. Unfortunately, the entire blower would need to be replaced.
Where is the fuse that controls the blower motor on a 1998 Chevy truck?
The fusebox which controls the blower motor is under the hood up by the firewall.
Why does the air conditoner blower go to full blast and not turn of after pressing power on a 2001 chrysler town and country?
If you have auto temp control, the blower motor power module has failed. It does the same job as a blower resistor. It is located behind the glove box.
What controls blower on 2000 mercury villager Estate?
The blower is controlled by the blower switch, blower resistor, and relevant power relay.
Where is the blower motor located on a 2007 Chrysler pacifica?
Blower motor resistors are usually located close to the blower motor.
Is there a second blower resistor in a 2002 Chrysler TC with rear air if so where is it?
If there is a second blower motor and speed control for the rear air, then there is also a second Resistor Pack. It will be located near the rear blower motor. Exactly I cannot say. Follow the wiring.
How do you replace a blower motor resistor and the pigtail that goes with it on a 2003 jeep grand Cherokee?
There are two screws holding it in. It is located underneath the glove box. Now Depending on if you have manual controls or auto controls will determine what you have to do. For auto controls the blower motor resistor gets plugged in with 3 wires (i believe its red black and orange) and then has two wires coming out of it that plug directly into the blower motor(red and black). For manual controls it is just plugged in and mounted. The purpose of the resistor is to eat up the juice of the battery to control the speed of the blower motor.
